Mini App Example

You can find this example in our Github repository:

ui-widgets-demos/thumbnail/005_file_thumbnail/src/main.py

Import libraries

import os

import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Card, Container, FileThumbnail
import supervisely.io.env as env

Init API client

First, we load environment variables with credentials and init API for communicating with Supervisely Instance:

load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))

api = sly.Api()

Prepare file and upload in Team files

team_id = env.team_id()
local_filepath = "/Users/almaz/job/text.txt"
remote_filepath = "/folder_thumbnail_demo/text.txt"

if api.file.exists(team_id, remote_filepath):
    api.file.remove(team_id, remote_filepath)

api.file.upload(team_id, local_filepath, remote_filepath)
# get file info from server
fileinfo = api.file.get_info_by_path(team_id, remote_filepath)

Initialize FileThumbnail widget

file_thumbnail = FileThumbnail(info=fileinfo)

Create app layout

Prepare a layout for app using Card widget with the content parameter and place widget that we've just created in the Container widget.

card = Card(
    title="File Thumbnail",
    content=Container(widgets=[file_thumbnail]),
)

layout = Container(widgets=[card])

Create app using layout

Create an app object with layout parameter.

app = sly.Application(layout=layout)
